US 8,302,209 B2 · Data processing methods and devices for reading from and writing to external storage devices

Abstract

A data processing device includes a data storage section that stores data; an authentication information storage section that stores first authentication information registered by a user; an input section that allows the user to input second authentication information; a first judgment section that permits reading of the data stored in the data storage section when the first authentication information matches the second authentication information, and does not permit reading of the data stored in the data storage section when the first authentication information does not match the second authentication information; a slot into which an external storage device can be inserted; and a writing admission section that permits writing of the data stored in an external storage device into the data storage section without input of the second authentication information when the external storage device is inserted into the slot.

Dependent claims

A data processing device comprising:

a data storage section that stores data;
an authentication information storage section that stores first authentication information registered by a user;
an input section that allows the user to input second authentication information;
a first judgment section that permits reading of the data stored in the data storage section when the first authentication information matches the second authentication information, and does not permit reading of the data stored in the data storage section when the first authentication information does not match the second authentication information by acquiring the first authentication information from the authentication information storage section when the second authentication information is input by the input section and by comparing the first authentication information with the second authentication information;
a slot into which an external storage device can be inserted;
a writing admission section that permits writing of the data stored in the external storage device into the data storage section without input of the any authentication information when the external storage device is inserted into the slot;
a registration section that registers at least one external storage device as a storage device from which data is permitted to be read when the at least one external storage device is inserted into the slot in the data processing device;
a second judgment section that permits reading of data stored in the data storage section when the external storage device is a registered external storage device and does not permit reading of the data stored in the data storage section when the external storage device is an unregistered external storage device by judging whether or not the external storage device is an external storage device registered by the registration section when the external storage device is inserted into the slot;
and
wherein the registration section generates authentication information and writes the generated authentication information into the external storage device inserted into the slot, and wherein the second judgment section reads the authentication information from the external storage device inserted into the slot and judges that the external storage device is a registered external storage device when the read authentication information matches the generated authentication information.

7 more elements

A method of controlling a data processing device including a data storage section storing data, an authentication information storage section storing first authentication information registered by a user, and a slot into which an external storage device can be inserted, the method comprising the steps of:

allowing the user to input second authentication information;
permitting reading of the data stored in the data storage section when the first authentication information matches the second authentication information, but not permitting reading of the data stored in the data storage section when the first authentication information does not match the second authentication information by acquiring the first authentication information from the authentication information storage section when the second authentication information is input by the input section and by comparing the first authentication information with the second authentication information;
permitting writing of the data stored in the external storage device into the data storage section without input of the second any authentication information when the external storage device is inserted into the slot;
registering at least one external storage device as a storage device from which data is permitted to be read when the at least one external storage device is inserted into the slot in the data processing device;
permitting reading of data stored in the data storage section when the external storage device is a registered external storage device and not permitting reading of the data stored in the data storage section when the external storage device is an unregistered external storage device by judging whether or not the external storage device is a registered external storage device when the external storage device is inserted into the slot;
and
wherein said registering comprises generating authentication information and writing the generated authentication information into the at least one external storage device when the at least one external storage device is inserted into the slot, and
wherein judging whether or not the external storage device is a registered external storage device comprises reading the authentication information from the external storage device inserted into the slot and judging that the external storage device is a registered external storage device when the read authentication information matches the generated authentication information.

5 more elements

A data processing device comprising:

a data storage section that stores data;
a host connecting section that is selectively connected to a host terminal as a device terminal and selectively allows the host terminal to read the data stored in the data storage section;
an authentication information storage section that stores first authentication information registered by a user;
an input section that allows the user to input second authentication information;
and
a first judgment section that allows the host terminal to read the data stored in the data storage section by allowing communication with the host terminal when the first authentication information matches the second authentication information and the host terminal is connected to the host connecting section, but does not allow the host terminal to read the data stored in the data storage section by not allowing communication with the host terminal although the host terminal is connected to the host connecting section when the first authentication information does not match the second authentication information by acquiring the first authentication information from the authentication information storage section when the second authentication information is input by the input section and by comparing the first authentication information with the second authentication information;
a slot into which an external storage device can be inserted;
a writing admission section that permits writing of the data stored in the external storage device into the data storage section without input of any authentication information and although the external storage device is not a registered external storage device when the external storage device is inserted into the slot;
a registration section that registers at least one external storage device as a storage device from which data is permitted to be read when the at least one external storage device is inserted into the slot in the data processing device;
a second judgment section that allows communication with the host terminal when the host terminal is connected to the host connecting section without input of any authentication information when the external storage device is a registered external storage device by judging whether or not the external storage device is an external storage device registered by the registration section when the external storage device is inserted into the slot;
and
wherein the registration section generates authentication information and writes the generated authentication information into the external storage device inserted into the slot, and wherein the second judgment section reads the authentication information from the external storage device inserted into the slot and judges that the external storage device is a registered external storage device when the read authentication information matches the generated authentication information.
